ABSTRACT:
A system for applying pressurized anhydrous ammonia to soil. The system includes a tank for containing the pressurized anhydrous ammonia. An anhydrous ammonia meter is in fluid communication with the tank for dispersing controlled amounts of the anhydrous ammonia. A pressurization unit is also in fluid communication with the tank. The pressurization unit defines a pressurization chamber through which anhydrous ammonia from the tank is circulated. A heating system cooperates with the pressurization unit to heat the anhydrous ammonia within the pressurization chamber. The heated anhydrous ammonia is returned from the pressurization chamber to the tank. By adding the heated anhydrous ammonia to the tank, the pressure within the tank is stabilized or even slightly increased.
